Census of Population and Housing, 2000 [United States]: Public Law (P.L.) 94-171 Data (ICPSR 3144)

Principal Investigator(s):United States Department of Commerce. Bureau of the Census

Summary:

Public Law 94-171, enacted in 1975, directs the United
States Census Bureau to make special preparations to provide
redistricting data needed by the 50 states. It specifies that within
one year following the Census Day (i.e., for Census 2000 by April 1,
2001), the Census Bureau must send the governor and legislature in
each state the data they need to redraw districts for the United
States Congress and state legislatures. These files provide data in a
hierarchical sequence down to the block leve... (more info)

one year following the Census Day (i.e., for Census 2000 by April 1,
2001), the Census Bureau must send the governor and legislature in
each state the data they need to redraw districts for the United
States Congress and state legislatures. These files provide data in a
hierarchical sequence down to the block level (state, county, voting
district/remainder, county subdivision, place/remainder, census tract,
block group, block). The collection contains four tables: (1) a count
of all persons by race (Table PL1), (2) a count of Hispanic or Latino
and a count of not Hispanic or Latino by race of all persons (Table
PL2), (3) a count of the population 18 years and older by race (Table
PL3), and (4) a count of Hispanic or Latino and a count of not Hispanic
or Latino by race for the population 18 years and older (Table PL4).

The data are provided in three segments (files)
per state: the Geographic Header, Tables PL1 and
PL2, and Tables PL3 and PL4. The Geographic Header segments are
fixed-format ASCII text files, while the Table segments are
comma-delimited ASCII files. The Geographic Header has 80 variables
and the Table segments have 149 variables each, for a total of 378
variables when the segments are combined.

The SAS Merge Program
(Part 90) is provided, but not supported, by the United States Census
Bureau. Users will need to merge the three segments for each state
into a SAS dataset to use the data effectively.

The data file
numbers are not consecutive. They correspond to FIPS codes for
states.

Methodology

Data Source:

self-enumerated questionnaires

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:

Created variable labels and/or value labels.

Version History:

2013-05-24 Multiple Census data file segments were repackaged for distribution into a single zip archive per dataset. No changes were made to the data or documentation.

2006-01-12 All files were removed from dataset 90 and flagged as study-level files, so that they will accompany all downloads.

2006-01-12 All files were removed from dataset 86 and flagged as study-level files, so that they will accompany all downloads.

2006-01-12 All files were removed from dataset 84 and flagged as study-level files, so that they will accompany all downloads.

2006-01-12 All files were removed from dataset 83 and flagged as study-level files, so that they will accompany all downloads.

2006-01-12 All files were removed from dataset 81 and flagged as study-level files, so that they will accompany all downloads.

2004-08-20 The data definitions statements were corrected.
The codebook was replaced with an updated version and the Record
Layout for All Parts, Part 85, was removed because it had incorrect
variable locations.

2002-07-30 Part 86, Codebook for All Parts, has been resupplied by
the Census Bureau. Parts 83 and 84, SPSS and Stata Data Definition Statements
for All Parts, were added to the collection.

2001-05-29 Parts 83 and 84, SPSS and Stata Data
Definition Statements for All Parts, were added to the collection. SPSS and
Stata data definition statements were also added.
